The Robotic Third Hand: An Awesome 3D Printed Hand Attachment


This awesome 3D-printed hand attachment is named The Robotic Third Hand and will surely be extremely helpful if you’ve ever found yourself in need of extra helping hand. This wonderful creation by engineer Timothy Giles was developed as an entry for the Hackaday Everyday Carry Contest and is undoubtedly a winner in my eyes. The Robotic 3rd Hand is worn on the forearm uses a Trinket Pro as its brain. When requested it can hand you a tool that it holds, freeing you from fumbling for it or losing it.

The high-tech hand attachment is designed to hold tools like screwdrivers to make them more accessible than reaching for a table or toolbelt. The device is unobstructive and easy to use. It leaves both sets of fingers free for handiwork, but when a screwdriver is needed, the wearer is able to press a button and have the tool placed in their hand.

It incorporates an adafruit Power Boost 1000 instead of the 5V boost supply on the component list. The Power Boost 1000 is functionally the same so it is a good stand in. This allows the screw to securely hold the screwdriver tray while the arm that actuates the screwdriver tray can move freely.
